False advertising and deducting money after contract cancelled

Vodacom rewards called me offering a a contract that they said was a data contract and that I didnt have to use the sim but i could transfer the data to 5 different vodacom numbers. I signed up for this reason. I had them use my old prepaid vodacom number for this. Wen the contract arrived i called vodacom immediately to find out about activation. They then told me i could not transfer data to 5 numbers and that there was no such contract. I was immediately transferred to vodacoms rewards where they confirmed it was a mistake and that they would cancel the contract. I checked the sim the next day and it was not canceled as the data was loaded. I then contacted vodacom who said it was cancelled and my number was back to prepaid. Today i got billed for this contract that was cancelled. I did not want this contract. You falsely advertised this to me. You deducted money off my account which i know i will not get back. I am sending an email to your ceo in the morning. You are a disgusting service provider conning people into taking contracts.
